Process for the liquid treatment of textile fibre material

摘要

Textile fibre material is dyed particularly rapidly, uniformly and gently by evacuating it to dryness in a container, after which the dye liquor is introduced, avoiding an initial condensation in the fibre material, into the container. This is achieved by introducing the dye liquor at a low temperature coordinated with the vacuum, or preheating the fibre material to the necessary extent. After introducing the dye liquor, this is placed under a slight excess pressure and made to act on the fibre material, which is then dried in the container.
